SHADE-PULL.

Specification of Letters Patent.

Patented Aug. 12,1913.

T 0 all whom it may concern Be it known that I, JOHN L. LAKE, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Shade-Pull, of which the following is a specification.

My invention consists of a device applicable to a shade especially to the stick on the bottom thereof, whereby the shade may be readily Pulled down or controlled in raising, said device being composed of jaws which are pivotally connected members pendant therefrom, and a cam piece which is adapted to be interposed between said members, and lowered so as to spread the same whereby the jaws are forcibly compressed on the shade or stick, and so firmly connected thereto, said cam piece being adapted to be raised whereby the jaws may be released from the shade, said piece being furthermore adapted to pass the pivot of the jaws in either of its motions.

The invention is satisfactorily illustrated in the accompanying drawing, but the important instrumentalities thereof may be varied, and so it is to be understood that the invention is not limited to the specific arrangement and organization shown and clescribed.

Figure 1 represents a perspective view of a shade pull embodying my invention. Figs. 2 and 3 represent longitudinal sections thereof in directions at a right angle to each other. Fig. 4 represents a perspective view of a detached member thereof.

Similar numerals of reference indicate corresponding parts in the figures.

Referring to the drawings :1 designates jaws or clips which are connected by the pivot 2 and have extending downwardly therefrom the inturned tongues 3, which are so disposed that by separating the same, said jaws are brought toward each other and by pressing in said tongues toward each other, said jaws are separated, it being noticed that the jaws are adapted to be applied to the lower end of a shade 4:, and the stick 5, in a hem thereof, and embrace the same, each jaw being provided with spurs 6 which are adapted to pierce the material of the shade and adjacent portion of the stick and so take firm hold of the latter.

Between the tongues 3 is interposed the cam 7 which consists of a wedged shaped piece which is adapted to ride on the inner sides of said tongues and when lowered to force said tongues apart, it being noticed that the upper portion of the piece has a vertically extending passage 8 therein forming a bifurcation which freely straddles the pivot 2 so as to guide the piece in its vertical motions while the base of said passage is adapted to abut against said pivot, limits the ascent of the piece and prevents its displacement from the jaws, but said passage allows the cam to be raised to the greatest possible extent so that the sides of the cam move from the inner faces of the tongues 3 to allow the latter to be brought together sufiiciently to cause the jaws or clips 1 to separate from the shade to permit the device to be removed fully therefrom.

Depending from the closed base of the cam is the ring 9, which is adapted for connection of the shade cord 10 therewith, it being seen that said ring freely occupies the space between the lower ends of the tongues so as not to interfere with the free vertical motions of the cam, in which motions said ring rides on said ends and acts as a guide preventing side turning of the cam.

The operation is as follows :The cam is raised so as to be removed partially from the tongues 3 whereby the jaws separate or may be separated, and the latter may be placed on the shade on opposite sides of the stick. Then, the cam is lowered, whereby it rides against the tongues 3 and by its wedging nature forces apart said tongues. This forces in the jaws and closes them tightly against the shade and stick, so that the jaws take firm hold on said stick, the device providing an efficient pull for the purpose intended, it being evident that the cam is gravitating in its nature and so will not rise and release the jaws, unless the latter is in tended in which case the cam may be lifted when the tongues are uncontrolled by the same, and the jaws separate or may be separated, and so withdraw from the shade, the pull thus being disconnected.

Having thus described my invention what I claim as new and desire to secure by Letters Patent, is

1. A shade pull composed of jaws, a pivot downwardly from said jaws, and a movable 10 wedge shaped cam interposed between said tongues, said camhaving 1n its upper portion a vertically extending passage which is sage whose walls are adapted to freely straddle said pivot.

2. A shade pull composed of jaws, a pivot connecting said jaws, tongues extending adapted to receive freely said pivot.
